WebIn physics, the term work has a very specific definition. Work is application of force, f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is … Web4 nov. 2024 · The work done on the ball by the external force is − m g h with the negative sign there because the direction of the external force (downward) is in the opposite direction to its displacement (upward). So − E i n i t i a l = − m g h ⇒ E i n i t i a l = m g h. During this time the acceleration of the ball a = g is downwards.
